Rotella T 14w40 38.67%


Hmm? The majority is using a nonexistant mystery oil. Must be good stuff.

 

Aw give the guy a break! I under estand he also has a peach inspediment.

 

I use John Deere plus 50. If it works for a tractor it will work foe me.

 

Amsoil 15w40 it wasn't on the poll so I voted other.

 

Hey you missed the AMSOIL 15W 40 Heavy Duty Diesel Oil.

 

Valvoline Premium Blue Extreme synthetic blend here.

 

Cen-Pe-Co S3 series 15W-40.

 

Delo for me in my current and past diesel trucks.......I believe in it and buy it for a fair price of $32.00 a case (6-GALLONS/2-oil changes) at COSTCO.

 

Rotella-T 5W40 Full Synthetic....I started using it in December around 21k miles, and even with the crappy winter blend diesel fuel, I've seen a slight mpg increase. Still has the Shell Stinky for a few hundred miles after the change, too.

Valvoline Premium Blue here too. Just picked up 31 quarts at the local wal-mart on clearance! $1.00 a piece. They will no longer carry that weight.
